Abstract: A vehicle structure according to an aspect of the present disclosure includes: a body; a bumper reinforcement disposed at a front or a rear of the body; and a crash box, one end of the crash box being joined to an outer end of the body in a front-rear direction and the other end of the crash box being joined to the bumper reinforcement, in which at least one of the body and the crash box is formed of a resin-coated steel plate, and a resin layer of the resin-coated steel plate is formed on a contact surface between the body and the crash box.

Abstract: A vehicle roof capable of ensuring a rust prevention property while preventing or reducing the increase in cost is provided. A vehicle roof includes an attachment part to which a hinge is attached. The attachment part includes a steel plate, and a first resin layer covering a surface of the steel plate on the side on which the hinge is located. The surface of the steel plate of the attachment part on the side on which the hinge is located is coated with a first resin layer. The first resin layer is thicker than a hinge resin layer covering the hinge. According to the structure of the vehicle roof, it is possible to ensure a rust prevention property while preventing the increase in cost.
